How do you calculate work from a word problem when you are only given mass, distance traveled and time it took for this distance to be traveled?

You have to remember that

Work Done = Force \times Distance

Force is also weight, given by, F=ma or W=mg, both are correct and will give you the same answer. (a = g = 10m/s^-2 {or 9.81 if you need more significant figures})

You're also given time here, which is not necessary to find the work. With that time, you can however, find the power, given by

Power = Work Done / Time

Hope it helped! :)
